Hello, welcome to the official website of Jinan Taihao Petrochemical Fittings Co., Ltd!

Jinan Taihao Petrochemical Fittings Co., Ltd. is located in Fenghuangshan Industrial Park, Pujizhen, Zhangqiu District, Jinan City, Shandong Province. Established in October 1996, the company currently has 80 employees, including 10 engineering and technical personnel. Registered capital: 30 million yuan; annual output value: 60 million yuan. The company produces various standard flanges and non-standard forgings, mainly including flanges conforming to Chinese standards (GB, HG, JB), American standards (ASME series), German standards (DIN series), British standards (BS4504 series), Japanese standards (JIS series), Italian standards (UNI), and Australian standards (AS).

Jinan strengthens the production of short-circuit manufacturers. Forged pipe fittings mainly include forged flanges, forged reducers, and forged tees. Corresponding to forged pipe fittings are cast pipe fittings. The mechanical properties of castings are lower than those of forgings of the same material. Cast pipe fittings melt metal into a liquid that meets certain requirements and pour it into a mold. After cooling, solidification, and cleaning, a casting (part or blank) with predetermined shape, size, and performance is obtained. This is the process. Using forging machinery to apply pressure to metal blanks to cause plastic deformation to obtain forgings with certain mechanical properties, shapes, and sizes. Through continuous hammering of the pipe fittings, the original segregation, looseness, pores, and slag inclusions in the ingot are compacted and welded, making the structure more compact and improving the plasticity and mechanical properties of the metal. Jinan Taihao Petrochemical Fittings Co., Ltd. is a professional manufacturer of accessories for water and electricity, petrochemicals, and pressure pipelines. It mainly produces high, medium, and low-pressure flanges and forged pipe fittings. The company has successively passed ISO9001-2008 quality management system certification, ISO14001-2004 environmental management system certification, and GB/T28001-2011 occupational health and safety management system certification. On June 19, 2013, it obtained the People's Republic of China special equipment (pressure pipeline components A-level) manufacturing license and has been awarded the Jinan "Contract-Honoring and Credit-Keeping" unit title for many consecutive years, receiving positive feedback from users!!

A flange connection involves securing two pipes, fittings, or components to flanges, placing a gasket between the flanges, and fastening them together with bolts. Some fittings and components already have flanges, which also constitute a flange connection. Flange connections are an important connection method in pipeline construction. They are convenient to use and can withstand considerable pressure. Flange connections are widely used in industrial pipelines. In homes, the pipe diameter is small and the pressure is low, so flange connections are not visible. In a boiler room or production site, however, pipelines with flange connections are everywhere.

Common models of duplex stainless steel flanges include S22253, S22053, and S23043. Duplex stainless steel flanges combine the characteristics of austenitic and ferritic stainless steels. Compared with ferritic stainless steel, they exhibit higher plasticity and toughness, no room temperature brittleness, and significantly improved weldability and resistance to intergranular corrosion. They also retain the high thermal conductivity and superplasticity of ferritic stainless steel, while exhibiting high strength and significantly improved resistance to intergranular corrosion and stress corrosion cracking compared to austenitic stainless steel flanges. Duplex stainless steel flanges also possess excellent resistance to pitting corrosion.
